apriori算法报错

[yongzhuo]

将输入数据改为如下形式（l5改为l10），报错:

datas =   [['l1', 'l2', 'l5'], ['l2', 'l4'], ['l2', 'l3'],
                    ['l1', 'l2', 'l4'], ['l1', 'l3'], ['l2', 'l3'],
                    ['l1', 'l3'], ['l1', 'l2', 'l3', 'l5'],
                    ['l1', 'l2', 'l3'], ['l1', 'l2', 'l10'],]

报错信息如下:
